Advancing the Room: Success with Digital Wireless Systems
Whether you are planning a permanent installation, an event, or a major tour date, the best way to ensure that your wireless systems provide great performances is by properly “Advancing the Room.” A tried and true method in the professional AV world, advancing the room is the practice of determining the best deployment profile of your wireless systems given the space where the gear will be operating and whether your event calls for many wireless channels, or just one. This guide outlines the steps involved in advancing the room so that you and your customers get the full performance benefits of Line 6 digital wireless systems.
STEP 1: ANTENNA PLACEMENT
Line 6 digital wireless systems offer many advantages, including easy, one-step setup and license-free operation worldwide. There is no need to check frequency tables, consult intermodulation calculators, or worry about matching hardware frequency band designations. Simplified setup and straightforward operation mean that you can focus on optimizing your antenna setup. Proper setup and antenna placement will ensure top system performance throughout its range.
During setup, it is best to orient the wireless transmitter and receiver along the same plane so that the receiver can take advantage of both antennas, as per the below diagram.
Then be sure to place the receiver’s antennas 90 degrees apart. Any of the below antenna placements are valid, so choose whichever placement is most appropriate for your setup. With proper antenna placement, the performer is free to move around the performance area; as the signal to one antenna becomes weak, the other antenna will become proportionally stronger.
Note that transmitters should always be at least six feet away from their receivers.
Your wireless receivers should be placed at least three feet above the floor in order to minimize RF reflections, and ideally the antennas should be raised just over the the heads of your audience, but not high overhead or up near the ceiling. Proper antenna height will maximize the range of your wireless system.
While 2.4GHz signals can travel through walls and around corners to a certain extent, it is best to maintain—as much as is reasonably possible—a direct, unobstructed line of sight between the transmitters and receivers. Avoid placing the receiver in the bottom of the rack unless remote antennas are employed. Avoid placing the receiver in close proximity to RF-generating equipment including computers, wireless access points, in-ear monitor systems, and microwave ovens.
